In terms of "work the host has to do", I would say that there is no difference between all the methods EXCEPT for manual, they are all automatic and decided by the upstream devices.
Manual requires someone to actually configure the IPs, but all other methods require no host configuration at all. Am I correct?
In IPv4 you have 2 methods of address assignment:
1) Manual
2) DHCP
In IPv6 there are 3 methods:
1) Manual
2) SLAAC (possibly still using DHCPv6 for other info)
3) DHCPv6 (still requires RA's for DG assignment)
Thanks!
